Disposable Suction Liners are designed to effectively and safely collect and contain fluids and secretions extracted during suctioning. Each premium-grade liner is ultrasonically sealed to the lid—eliminating the need for assembly for time-saving convenience. A patient-port elbow adaptor allows for effortless hookup and helps to reduce the risk of kinked tubing. The liner features a mechanical shutoff valve to help prevent cross-contamination of wall vacuum outlets.
